Application filed May 18,

To all whom it may concern: 7

Be it known that I, JOHN (i. Joi-rNsoN, a

citizen of the United States, and resident of the city of Tacoma, county of Pierce and In accomplishing the objects of the inven-;

tion, I have provided the improved details of construction, the preferred form of which is illustrated in the accompanying drawings, wherein- Fig. 1 is a side view of a fan belt constructed according to the present invention; a part of the binding strip being removed for better illustration.

Iilig. 2 is an enlarged view of: a part of the belt.

lfiig. 3 is a transverse sectional the same.

v i cw of Fig. t is a transverse sectional view of a belt of a different shape.

Referring more in detail to the drawings 1 designates a fan belt constructed according to the present invention, which in its preferred form consists of an endless core or belt body, formed of a plurality of strands 2 of rope, or the like, which are interwoven, twisted together or arranged parallel to each other in an endless core of any desired length BELT.

and bound together Within a casing formed of an endless strip 8 of pliable material such as leather or fabric which is wound spirally thereabout.

In order to prevent slipping 01 this binding on the core or body of the belt, the strip is extended between strands of the body at spaced intervals, as is shown particularly at l in Fig. 1.

While I have illustrated the belt as being roundin cross section, it isnot desired that the belt be made only in this form, as it is apparent that, as shown in Fig. t, by the proper placing and varying the number of strands used to make up the core, it may be made fiat, i -shaped or in other shapes;

It is apparent that a belt of this character would be strong, pliable and lasting and that cracking would be eliminated due to the flexibility of the'core strands and their casing or binding.

Having thus described my invention, what I claim as new therein and desire to secure by Letters Patent is: i w

An endless belt of the class described comprising a core formed 01'. a plurality of twisted or interwoven strands of cording and a casing applied to said core comprising an endless, flat strip of flexible material wound spirally on the core with the convolutions thereof close together to entirely cover the core and forming a smooth exterior surface, and said strip being extended at intervals beneath strands of the core for the purpose set forth.

Signed at Tacoma, Washington, this 11th day of May, 1920 JOHN G. JOHNSON.
